Parameter introduction:
1. Product name: PCM1794A DA Convertoer2. Version: V3.03. Product size: 79mm*50.5mm(L*W)4. Input method: IIS5. Support format: 24Bits pcm 192khz6. Voltage input: logic voltage DC 5V Analog voltage DC + 15v 0v -15V...
The correction of GMT0 in the chart is FMT0, which is consistent with the board:MUTE status 0 Non-silent 1 MuteRealize mute function, output is no sound output:DEM status 0 Non-resampling 1 ResamplingTo achieve resampling function, all input signals will be converted to 44.1khz for decoding.
Introduction:
1. The analog circuit refers to the LUXMAN high-end CD circuit improvement, and its sound reaches 90% close to LUXMAN da06. The PCM1794A is the classic decoding chip only for the PCM1792A. The sound becomes atmospheric, medium-medium frequency, low frequency The strength is strong and powerful, and the high frequency is crystal clear. It's not too much to use these highly flamboyant words to describe it.2. The design of the whole board is reasonable, the analog circuit is almost designed with symmetrical lines, and strict design standards are followed, so that the entire product index reaches more than 95% of the chip index, and the performance of the chip is almost perfect. In terms of materials, high-precision imported resistors are used. Logic circuits use fevered imported tantalum capacitors, and analog circuits use fevered imported WIMA capacitors. The sound from the entire decoding is impeccable.3. Those ESS9038 AKM4497 dare to say that the index is high in front of it, and almost bow their heads in other aspects. The most important thing for listeners is music. In addition to the very good indicators, PCM1794A takes into account the sense of music (including the vocal environment, sound field, sound background, noise floor, professionally referred to as the overall performance of signal-to-noise ratio, low frequency transient response)4. This is a very cost-effective board. After receiving the board, you are not satisfied with the sound. Welcome to give a bad review or a star.
